About this site

This site started from a simple frustration: most "free calculators" online aren't really free tools, they're lead magnets. You answer two or three questions, and instead of a real answer you get a soft pitch for a demo, a signup wall, or a page so cluttered with software ads that the actual calculator is an afterthought.

We wanted something different: a set of calculators that are genuinely complete on their own, with no account needed, no email required, and no product to upsell you on afterward. Just a working tool and a clear explanation of the math behind it.

How each tool gets built

Before building any calculator, we look at what already exists for that exact question, what the strongest competing tools do well, and where they fall short, whether that's a missing feature, a cluttered page, or assumptions the user can't see or change. Every tool here is built to close a real gap rather than duplicate what's already out there.

Where a topic has real complexity, different tax rules by location, employment law that varies by state or country, we say so directly instead of quietly picking one country's rules and presenting them as universal. Our calculators use transparent, editable assumptions instead of a fixed formula, so the tool works for you wherever you are, not just for one specific jurisdiction we happened to default to.

What these tools are, and aren't

Every calculator here is a planning tool. It takes the numbers you enter and does the math correctly and transparently. It is not tax, legal, accounting, or financial advice, and it doesn't know the specific rules that apply where you live or work. For anything with real financial or legal weight, use these tools to understand the shape of a decision, then confirm the specifics with a qualified professional.

How this site makes money

This site is supported by advertising, which is what lets every calculator stay free with no signup and no paid tier. We don't sell your data, and the calculators themselves don't send your inputs anywhere, everything runs directly in your browser.
